Bonding does not reduce the tooth's original structure. It is quick, painless and relatively inexpensive. Bonding generally requires very little drilling and most treatments can be performed in a single visit without the use of anesthetic.
The material used is a natural-colored, composite resin (or plastic) which is hardened with an ultra-violet light. A precise shade is selected to match existing teeth. The composite is then applied in fine layers, with each coat hardened slightly until the desired amount has been applied. After the final hardening stage, the bond is sculpted for the desired shape and texture.
It should be noted that cosmetic bondings, just like natural teeth, are subject to discoloration from coffee or tobacco. Bondings typically do not last as long as porcelain veneers and may require touch-ups or replacement in 5 to 10 years.
